Title: Vehicle hydraulic braking system
IPC: B60T8/22
Filed: 1965-01-15
Abstract: A vehicle hydraulic brake system comprising two separate fluid circuits connected to front brakes 6 and rear brakes 7 respectively, each including a fluid accumulator 3 or 4 and a distributer device 5a or 5b feeding fluid to the respective brake or set of brakes, the distributers being mounted in tandem and operable by a common pedal 10, is characterized in that one of the fluid circuits incorporates a limiting valve device 11 limiting the pressure applied to the brake or set of brakes of said one circuit as a function of the load on the axle associated therewith. The limiting valve comprises two integrally connected pistons 12 and 16 in a cylinder 13 defining a first chamber between said pistons connected to the rear brake outlet line 9a, and a further chamber 13a connected to said outlet line by a by-pass line 14 having a relief valve 15. An axial extension 12a on the piston 12 is adapted to abut the base of the cylinder whilst a second extension 17a is connected through a spring 20 to one end of a lever 22 which is pivoted to the vehicle chassis and abuts at its other end the rear axle 24. On depression of the pedal 10, accumulators 3 and 4, which are pressurized by a pump 1 from a reservoir 2, feed fluid through the respective distributers 5a and 5b and along lines 8 and 9 to front and rear brakes respectively. The pressure transmitted to the brake 7 also acts in chamber 13a on the underside of the piston 12. When this pressure balances the action of the spring 20, the piston rises and closes the end of the pipe 9 to limit the rear brake pressure to a value proportional to the compression of the spring 20 and hence the load on the rear axle 24. If the load on the axle 24 and hence spring 20 momentarily decreases during braking, due to, for example, road conditions or displacement of the vehicle centre of gravity, upward movement of pistons 12 and 16 is sufficiently large for the brake to be vented through pipe 9a and 18 to the reservoir to prevent locking of the wheels. In a modified embodiment, Fig. 2 (not shown), a pneumatic or hydropneumatic suspension bellows of the type wherein the distance between the chassis and the axle is maintained constant by modifying the bellows pressure as a function of vehicle load, is connected to a jack (27). The piston of the jack is either directly or indirectly connected to the valve extension 17. The valve device 11 may be fixed relative to the chassis or alternatively the valve device 11 may be fixed relative to the axle 24.

IPC: H01M6/22
Filed: 1967-09-23
Abstract: A cell according to the invention comprises at least 2 opposing electrodes and a gel between the electrodes and in contact with them, the gel comprising an aqueous electrolyte and a reaction product of (a) a water soluble synthetic organic polymer having anionic groups attached to the polymer chain and (b) a water soluble synthetic organic polymer having cationic groups attached to the polymer chain, the polymers being such that without the ionic groups they would be water-insoluble filmforming materials. The cell may be a leadsulphuric acid accumulator, a silver-zinc battery with an alkaline electrolyte, or a hydrogenoxygen fuel cell with an alkaline or sulphuric acid electrolyte. The ionic polymers should contain at least one ionic group per 6 monomer residues or per 12 chain carbon atoms. Its molecular weight may be 50,000 or more. Polymers specified are polymers and copolymers of sodium styrene sulphonate and vinylbenzyl trimethyl ammonium chloride, polyacrylic acid, hydrolysed copolymers of styrene and maleic anhydride, polyvinyl sulphonic acid, sulphonated polystyrene, sulphonated polyvinyl toluene and alkali metal salts thereof, polyethylene imine, polyvinyl pyridine, polydimethylamino ethyl methacrylate, quaternized polyethylene imine, quaternized dimethylaminoethyl methacrylate and polyvinyl methyl pyridinium chloride. The gel may be formed by adding the two polymers to separate aqueous media containing shielding electrolytes, e.g. NaBr or H 2 SO 4 or by dissolving preformed ionically cross-linked polymer. Up to 10 eq. of one polymer may be used per 1 eq. of the other. Solution may be facilitated by heating or adding a volatile water miscible organic solvent. Gelation may be effected by cooling the solution or boiling off some of the solvent. The gel may contain supporting woven or non- woven fibres of glass, polyethylene or polypropylene and the electrolyte may be added during or after production of the gel. The electrolyte mass may be shaped to fit the cell or made in situ in the cell.

Title: Fuel injection system for internal combustion engines
IPC: F02D41/30
Filed: 1967-11-04
Abstract: In an I. C. engine with fuel injection controlled electrically in accordance with the degree of vacuum in the inlet manifold, the fuel pump is automatically switched off at speeds below idling, to reduce loss of fuel due to faulty functioning, the switch circuit being cut-out at starting. As shown (Fig. 1), the four cylinders of an engine 10 are supplied with fuel through valves 13, obtained from tank 17 by pump 16 driven by motor 18. The engine drives a contact breaker 56, 57, 58 feeding two pulses per revolution to a monostable multi-vibrator 25 to produce a pulse train synchronous with the engine rotations whose durations are determined by the pressure in the inlet manifold 12, as measured by the displacement of core 41 of transformer 39, and extended when the engine temperature is low, as sensed by a temperaturesensitive resistor 67. These pulses are fed through synchronous switch 29 to the solenoid windings of the valves 13, and also to an averaging circuit comprising capacitor 72 in parallel with resistor 71. When the engine speed is above idling, the charge on capacitor 72 causes transistors 21, 22 to conduct and relay winding R is energized, contact r is closed and motor 18 is energized. When the speed falls below idling, the charge on capacitor 72 does not maintain transistor 21, 22 conducting and contact r opens, stopping the fuel pump 16. A switch 80 in the base circuit of transistor 21 is closed when starting, causing the transistor to conduct and close contact r independently of speed. In a modification the averaging circuit is fed from a separate monostable multi-vibrator so that the pulses being averaged are of constant duration.

Title: Hydraulic fuel oil pump or the like
IPC: F23K5/14
Filed: 1967-11-28
Abstract: A rotary positive displacement hydraulic pump of the internally meshing n and n + 1 tooth type includes a circular vortex chamber II, Fig. 2, wherein any air entrained with the liquid e.g. oil, that is to be pumped by a pair of gear-wheels 16, 17 is separated from the liquid by centrifugal action. The vortex chamber is defined by a cap 7 and a plate 31, and contains three radially orientated uniformly disposed ducts 10 having inlet ports 6 at their outermost ends through which the air and liquid aforesaid enters the ducts from a chamber 2 within a cover 3 attached to a housing 33, the liquid being in the lowermost part of the chamber 2 so that mostly air enters the uppermost duct 10. A vortex is formed in the chamber II owing chiefly to the provision of a suction port 36, Fig. 3, and a duct 11 in the plate 31, said port being adjacent the perimeter of the chamber and said duct being substantially tangential to said perimeter. Liquid is drawn off through the port 36 into suction chambers 14, 20 adjacent the gear-wheels while a light mixture of air and liquid collects at the centre of the vortex. Periodically, any surplus air in the vortex is also drawn through the port 36. A filter 4 and a rubber diaphragm 5 are lodged in the chamber 2, which is charged with liquid through two ducts (1, Fig. 1, not shown), in the housing 33, the diaphragm serving to minimize pressure fluctuations. Separation of air and liquid in the vortex chamber is said to reduce noise.

Patent ES-352388-A1 (ES)
Title: Drawing method and apparatus
IPC: B29C51/00
Filed: 1968-04-04
Abstract: In a process for cold drawing hollow articles from plastics sheet material, the sheet is initially peripherally clamped under a first pressure and, during the drawing operation, the pressure is reduced to a lower value. This prevents wrinkling and fraying of the lip of the article and increases its dimensional stability. In the described embodiment, the sheet is drawn between co-operating male and female dies 16 and 32 and is initially applied by the female die against an annular draw pad 26 having an outer peripheral ridge 40. In operation, the sheet is initially clamped against the ridge by forward movement of the female mould, further movement of the mould causing the sheet to be drawn over the male mould. At a predetermined instance during the drawing stroke, the sheet is completely drawn off the ridge into the larger gap adjacent thereto thus causing the desired decrease in clamping pressure on the sheet.

Title: Fuel injection system for internal combustion engines
IPC: F02D41/32
Filed: 1969-02-12
Abstract: In an I.C. engine fuel injection control system, the duration of solenoid operable injection valve opening pulses, from a multi-vibrator 28, Fig. 1, is determined as a function of the absolute pressure in the intake manifold 12 and the difference between the intake manifold pressure and the environmental barometric pressure, the construction of the pressure transducer being such that the valve opening period is controlled to provide maximum engine performance at all speeds and at all altitudes, less fuel being required at higher altitudes. The transducer 37, Fig. 4, includes a housing divided by a diaphragm 86 into two chambers 104, 105, chamber 104 being connected to atmosphere via passage 106, and chamber 105 being connected to the intake manifold via passage 38. The diaphragm is movable between two steps 87, 102. At low speeds i.e. low intake manifold pressure, diaphragm 86 abuts step 87 and a core 129 is positioned relative to two coils 118, 119 which control the multi-vibrator 28. As the engine speed increases, the intake manifold pressure increases thus causing pressure in chamber 105 to compress vacuum-diaphragm box 138 to move core 129 downwardly and thus increase the inductance of coils 118, 119 to increase the pulse duration. At a predetermined pressure, diaphragm 86 moves away from step 87 to further increase the inductance of coils 118, 119 and thus the pulse duration, the movement being limited by step 102. At the maximum speed the intake manifold pressure equals the atmospheric pressure. In Figs. 7 and 8 (not shown), the difference between the graphs of intake manifold pressure v pulse duration at sea level and at high altitude is illustrated. The shape of these graphs are also dependent upon the shape of core 129, the characteristics of diaphragm boxes 138, 140 and the spring rate of spring 146, leaf-springs 123, 124, which centre the core 129, and diaphragm 86. For altitude compensation at low engine speeds, the step 87 may be replaced by a resilient disc (160) having holes therethrough so that the pressure in chamber 105 acts on diaphragm 86, and the step 102 may be omitted, Figs. 9 to 12 (not shown). Further the diaphragm 86 may be omitted, Fig. 3 (not shown). The pulse duration may be additionally dependent upon engine speed and temperature.
